BACKGROUND

1. Technical Field

The present disclosure relates to a vessel. More particularly, the present disclosure relates to a vessel preventing liquid leakage.

2. Description of Related Art

In general, a vessel is for containing various objects or liquid food. The vessel usually has a lid and a container. The lid is used to seal the container. In order to contain a variety of objects or liquid food, a variety of vessels with different sizes and shapes are provided. High sealing is very important when the container is used to contain a liquid.

One conventional vessel utilizes a plurality of spiral portions to enhance the seal between the lid and the container. However, the seal of this conventional vessel is not enough to prevent liquid leakage because of the gaps in these spiral portions. Another conventional vessel uses some vertical convex and concave portions to engage the container with the lid. Unfortunately, the seal of this conventional vessel is also not enough to prevent liquid leakage due to the poor seal between the vertical convex and concave portions. Therefore, a vessel having a reliable seal and a lid that can be easily opened and sealed is commercially desirable.

In the embodiment, the lid tab 400 is triangular. The edge structure 330 includes a container tab 500 connected to an edge of the sixth inclined portion 335. In the embodiment, the container tab 500 is triangular. The container tab 500 can be triangular, rectangular or semicircular. Moreover, in order to easily separate the lid 200 from the container 300, the lid tab 400 and the container tab 500 both have rugged surfaces. For example, a plurality of protruding structures can be formed on the rugged surfaces.

FIG. 3 is another cross-sectional view of the container 300, in which the container 300 is sealed by the lid 200. As shown in FIG. 3, the edge structure 330 is engaged with the brim structure 220, and the container 300 is sealed by the lid 200. Specifically, the first side portion 221 is adjacent to the second side portion 331. The first horizontal portion 222 is adjacent to the second horizontal portion 332. The first inclined portion 223 is adjacent to the third inclined portion 333. The second inclined portion 224 is adjacent to the fourth inclined portion 334. The fifth inclined portion 225 is adjacent to the sixth inclined portion 335.

FIG. 3A is a partial and enlarged cross-sectional view of the vessel 100 of FIG. 3. FIG. 3B is another partial and enlarged cross-sectional view of the vessel 100 of FIG. 3, in which the vessel 100 is in an inclined state (i.e., the bottom 310 is not parallel with the horizontal line.) As shown in FIG. 2A, FIG. 3A and FIG. 3B, the first side angle θ7 is equal to the second side angle θ8. The first inclined angle θ1 is equal to the third inclined angle θ3. The second inclined angle θ2 is equal to the fourth inclined angle θ4. The fifth inclined angle θ5 is equal to the sixth inclined angle θ6. Therefore, the edge structure 330 can be tightly engaged with the brim structure 220 so as to increase the seal degree of the vessel 100. The first side angle θ7 and the second side angle θ8 are both greater than 60 degrees and less than 90 degrees. The first inclined angle θ1 and the third inclined angle θ3 are both greater than 60 degrees and less than 90 degrees. The second inclined angle θ2 and the fourth inclined angle θ4 are both greater than 30 degrees and less than 60 degrees. The fifth inclined angle θ5 and the sixth inclined angle θ6 are both greater than 45 degrees and less than 90 degrees. Particularly, the fifth inclined angle θ5 and the sixth inclined angle θ6 are greater than the second inclined angle θ2 and the fourth inclined angle θ4, respectively. As shown in FIG. 2A, when the first inclined angle θ1 and the first side angle θ7 are between 60 degrees to 90 degrees, a trapezoidal cross-section shape is defined by the first side portion 221, the first horizontal portion 222 and the first inclined portion 223, in which the trapezoidal cross-section shape is wide at the top side and narrow at the bottom side. In a similar fashion, when the third inclined angle θ3 and the second side angle θ8 are between 60 degrees to 90 degrees, a trapezoidal cross-section shape is defined by the second side portion 331, the second horizontal portion 332 and the third inclined portion 333, in which the trapezoidal cross-section shape is also wide at the top side and narrow at the bottom side. As a result, the tight degree between the lid 200 and the container 300 is increased. Accordingly, when the vessel 100 is tilted, the vessel 100 with trapezoidal cross-section shapes can effectively prevent the liquid contained therein from leaking out.

According to the aforementioned embodiments and examples, the advantages of the present disclosure are described as follows.

First, the brim structure and the edge structure with trapezoidal cross-section shapes which are wide at the top sides and narrow at the bottom sides are adopted. The vessel an prevent objects or liquid contained therein from falling out or leaking out.

Second, using a number of non-vertical inclined portions and horizontal portions can effectively increase the sealing of the lid and the container. This structure of the vessel is very simple and low cost.
